Hand Thinning of Fruit Trees

News Article

Fruit trees loaded with fruit should be hand thinned to

  1. obtain large, high quality fruit at harvest;
  2. allow development of flower buds for next year's crop, thus overcoming the tendency for some fruit trees to bear fruit in alternate years; and
  3. prevent limb breakage.

Hand thinning of apples should be done within 6 weeks of full bloom or by approximately mid-June. Leave the largest apple in a cluster unless it is damaged. After thinning, the apples should be spaced about 8 to 10 inches apart on the branches. Pears, plums, and apricots should be spaced about 6 to 8 inches apart on the branches.
